Kope winder or friction winder ppt
Friedrich Koepe invented the Koepe winder, or friction winder, in 1873 as an alternative to traditional winding drums. A Koepe winder replaces the winding drum with a large wheel or sheave that the cages are connected to by rope. The rope passes around approximately 200 degrees of the sheave, which provides friction to drive the rope instead of a drum. Koepe winders can be ground-mounted or tower-mounted. They are often used for hoisting heavy loads from deep shafts due to avoiding the large inertia of a winding drum. Power calculations consider static torque from unbalanced loads, dynamic torque from acceleration/deceleration, and torque to overcome friction between the rope and she

RAILWAYS,HARBOR, TUNNEL ENGINEERING
This document discusses tools and equipment used for railway track maintenance. It outlines the objectives of maintenance to prolong the life of tracks and rolling stock and increase safety. Good maintenance allows for higher train speeds, fuel savings, and more passenger usage. Tracks require maintenance due to deterioration from train loads, weathering, and curvature effects. Maintenance includes daily checks using hand tools and periodic rebuilding every 2-3 years using both hand tools and mechanical equipment like lifting jacks and tampers to realign tracks, level ballast, and replace worn components like crossings and tunnels. Common hand tools are rail gauges, spanners, picks, shovels and levels, while mechanical tools help lift and align larger sections of track.
Defects and inspections of water supply system
The water supply system conveys water from its source through miles of piping to taps using pumps and valves. Common defects in water supply systems include rusting, leakage, dents and buckles, blockages, and cracks. Operators inspect for these defects and remedy them by replacing old pipes, tightening joints, removing blockages, and repairing cracks through welding. Regular inspection and maintenance of pipelines is important to detect defects early and prevent failures.

Nathan Welsh: Northparkes Mines - Winder East Skip Derailment
This document summarizes a derailment incident of the east skip at Northparkes Mines' main winder. The incident occurred on March 10, 2015 at 1:38am when the lower shoes on the east skip did not engage with the fixed guides at the loading station, damaging structural beams. An investigation identified misalignment of the conveyance due to a failed west shoe and induced conveyance oscillation from acceleration/deceleration as contributing factors. Controls were implemented to address these factors before resuming production, including slowing the skip near fixed guides and improving guide rope lubrication and inspection. However, a root cause could not be definitively determined.
presentation on mobile cranes
Cranes are used to lift and lower materials in construction and manufacturing. They can be mounted on vehicles or structures. Operators control the crane and communicate with workers through signals. The largest revolving cranes are found on ships. Common types include mobile, overhead, gantry and tower cranes. Unstable loads, lack of communication, lack of training, and inadequate maintenance or inspection are major causes of crane accidents that can injure operators or others in the area. Regular inspections by a competent person help ensure cranes are safe to use.

Corrugated (roaring), Hogging, Buckling, Kinks in rails
This document discusses various types of defects that can occur in railway tracks, including corrugated rails, hogged rails, buckled rails, and kinks in rails. Corrugated rails, also known as roaring rails, develop minute depressions on the rail head surface that cause noise when trains pass over. Hogged rails occur when rail ends are bent down due to wheel battering. Buckled rails happen when expansion gaps are insufficient and prevent rail expansion in hot weather. Kinks form at rail joints when ends move out of position, causing jerky movement. The document provides details on the causes and remedies for each type of defect.

The Evolution and Impact of OTT Platforms: A Deep Dive into the Future of Ent...
This presentation provides a thorough examination of Over-the-Top (OTT) platforms, focusing on their development and substantial influence on the entertainment industry, with a particular emphasis on the Indian market.We begin with an introduction to OTT platforms, defining them as streaming services that deliver content directly over the internet, bypassing traditional broadcast channels. These platforms offer a variety of content, including movies, TV shows, and original productions, allowing users to access content on-demand across multiple devices.The historical context covers the early days of streaming, starting with Netflix's inception in 1997 as a DVD rental service and its transition to streaming in 2007. The presentation also highlights India's television journey, from the launch of Doordarshan in 1959 to the introduction of Direct-to-Home (DTH) satellite television in 2000, which expanded viewing choices and set the stage for the rise of OTT platforms like Big Flix, Ditto TV, Sony LIV, Hotstar, and Netflix. The business models of OTT platforms are explored in detail. Subscription Video on Demand (SVOD) models, exemplified by Netflix and Amazon Prime Video, offer unlimited content access for a monthly fee. Transactional Video on Demand (TVOD) models, like iTunes and Sky Box Office, allow users to pay for individual pieces of content. Advertising-Based Video on Demand (AVOD) models, such as YouTube and Facebook Watch, provide free content supported by advertisements. Hybrid models combine elements of SVOD and AVOD, offering flexibility to cater to diverse audience preferences.
Content acquisition strategies are also discussed, highlighting the dual approach of purchasing broadcasting rights for existing films and TV shows and investing in original content production. This section underscores the importance of a robust content library in attracting and retaining subscribers.The presentation addresses the challenges faced by OTT platforms, including the unpredictability of content acquisition and audience preferences. It emphasizes the difficulty of balancing content investment with returns in a competitive market, the high costs associated with marketing, and the need for continuous innovation and adaptation to stay relevant.
The impact of OTT platforms on the Bollywood film industry is significant. The competition for viewers has led to a decrease in cinema ticket sales, affecting the revenue of Bollywood films that traditionally rely on theatrical releases. Additionally, OTT platforms now pay less for film rights due to the uncertain success of films in cinemas.
Looking ahead, the future of OTT in India appears promising. The market is expected to grow by 20% annually, reaching a value of ₹1200 billion by the end of the decade. The increasing availability of affordable smartphones and internet access will drive this growth, making OTT platforms a primary source of entertainment for many viewers.
